Top Commenters

I think you should have a "Top Commenters" list for witty users somewhere. It would rank users via reputation points in particular time frames. Similar to "Today's Best Comments" but more in depth. Divide them up between "Daily/Weekly/Monthly/All-time." It would list the most witty users with recent comments and then possibly add subscriptions as an option to follow them. Then your reputation points would actually give you reputation. And add visibility to every imgurians awesomeness!

I think this would add to the interactivity(?) of the site. Just a thought.
